After a recent upgrade of our MiCollab environment, CI is no longer working. In MCS, after ticking the box "Enable Calendar Integration" and clicking on 'Test Connection' (using my username/password), I get the dreaded "Invalid calendar server credentials.: Invalid credentials."
I've been working with our partner as well as searching high/low on my own for a solution, and am not having any luck. I've tried following the suggestions in other threads related to IIS and enabling "Basic and/or Digest" authentication on \EWS, restarting IIS, and then walking through the steps above again and had zero luck.
Server Version: 8.0.2.10
Client Version: 8.0.303 (build: 40)
Exchange Server 2010, SP2
Anybody know if CI still works with the server/client versions noted above? Also, we're planning an upgrade to Exchange 2016 in the next month or so, does CI work with this version of Exchange?
Thank you for any feedback/help
